Apache::AuthCookie allows you to intercept a user's first unauthenticated
access to a protected document. The user will be presented with a custom
form where they can enter authentication credentials. The credentials are
posted to the server where AuthCookie verifies them and returns a session
key.

Update to 3.23
---------------
3.23 2015-09-10
- Improve CGI mode param() handling to avoi CGI.pm's "param() called in \
list context" warning.
- add support for Apache 2.4 via mod_perl 1.09.
***** IMPORTANT *****
Apache 2.4 has a *VERY* different API for authentication. You will need
to port your subclass and configuration over to the Apache 2.4 API in
order to use Apache 2.4! Please be sure to read README.apache-2.4.pod for
porting instructions!
